Key Concepts in Ligand Design: An Introduction

WebMany ligands are capable of binding metal ions through multiple sites, usually because the ligands have lone pairs on more than one atom. Ligands that bind via more than one atom are often termed chelating. A ligand that binds through two sites is classified as bidentate, and three sites as tridentate. WebMononuclear complexes of O 2. O 2 binds to a single metal center either “end-on” (η 1-) or “side-on” (η 2-).The bonding and structures of these compounds are usually evaluated by single-crystal X-ray crystallography, focusing both on the overall geometry as well as the O–O distances, which reveals the bond order of the O 2 ligand..
